To @ZZ whom it may concern:

Be it lrnown that l, MARTIN SAND, a citizen of the United States, residing at Tunbridge, in the county of Pierce and State of iorth Dakota, have invented new and useful improvements in Cultivators, of vwhich the following' is a speciiication.

The obj ect of this invention is to provide acultiator capable of following after a twenty-shoe drill, to stop drifting and to 1Kill weeds` `With this and other objects in view, as will be hereinafter. more fully pointed out, reference will be had to the accompanying drawings forming a part of this specification and wherein like numerals of reference designate corresponding parts throughout the several views, in which Fig. 1 is a top plan view of the invention complete, withthe single exception that the draft tongue is broken off,

F ig. 2 is a view in side elevation 0f the invention, with the draft tongue broken 0E,

Fig. 3 is a vertical sectional view of the front wheel portion of the invention,

Fig. l is a top plan fragmentary View taken on the plane 4--4 of Fig'. 2, and

Fig. 5 is a perspective view of the combined locking and guiding handle.

Referring to the accompanying drawing, reference numeral 1 designates the front wheel, 2 the rear wheels, 3 the rear axle attachedsuitably beneath a rectangular body frame which isycomposed of two doubletimber side beams 1, connected at their front ends by front beam 5 and at their rear ends by rear beam 6. |The front frame beams together with the Vforward ends of the side beams e rest upon a sill 7, (see Fig.v 2) and this sill, in turn, rests upon the main cultivator tooth carrying beam, which extends considerably beyond. each rear wheel on both sides of the main frame.

Extending centrally of the main body frame is a center sill or beam 8, secured at its rear end of the rear frame member 6, to the axle 3, and to the front frame mem?- ber 5, and thence extends forwardly as one piece, or as a separate piece 9. ln the drawings, the parts 8 and 9 are separate, being connected by upper and lower straps 10, bolted through and through as at 11, and advantage may be taken of this construction to secure the seat 12 in place, as illus trated in detail in Fig. 3. This part 9 is arched and terminates in a head 14 in which hasta is vjournaled the stem 15 Vof the front wheel l A fork 16. The front wheel 1 is journaled in the lower ends of the fork, furcations, and is turned to guide the cultivator by means of a handle 17 or draft tongue 18 as the case may be as will be later explained. The draft tongue 18 rests upon the frame head 14 and swivels on the stem 15, being held from vertical movement on the stem by a collar 19fsecured to the stem by pin 20. The upper end ofthe stem 15 -is squared and the said handle lever 17 is centrally fulcrumed at 21 thereto, and "its forward end is providedl with'a locking tooth' or pin 22 extending downwardly and adapted to be inserted or withdrawny from a recess 24 formed in the draft tongue 18, so that the front wheelmay be turned for guiding by means of the handle'lever 17 solely, or by means of the draft tongue throughthe han-v dle lever 17 interlocked at 22-214 therewith. llhe front fork is provided on each side with a foot rest 25, which also serves as an aid in manual guiding. Y

Extending transversely7 across the machine at rthe frontl thereof isa lguide member, looped at its center 27 to'encircle a ,pin 28' and extending outwardly as outriggers on opposite sides thereofand theseV outriggers have their outer ends'bent downwardly as at 29, in Fig. 2, and their extreme lower ends formed with eyes 30 'and through these eyes extendthe forward ends of the draft rope 31. rlhe central portion of this rope passes across infront of the frame beam 5 which' latter has at its ends the guide pulleys 32 through which also the draft rope 31 passes. At the` free forward ends, the draft rope is equipped with trees 32,'one on each side of the machina-and while these are shown as hanging ydown in full linesV in Figs. `1v and 2'it will be understood that in operation, they assume the dotted line position of both Figs. 1 and 2, and any un# equalities in draft maybe compensated for by the'draft rope passing through the pulleys from one side to the other according to theV amount of pull on one side or the other. Y

The main cultivator tooth carrying beam 40 on its rear side is provided with eyes 41 spaced at regularintervals and through their eyes having the pintle rod 42 extending. The outer ends of this rod 42 are bent upwardly as at 42 and'secured lin the model in cut out `portions 43, see Fig.2, by pins 44, though obviously the terminal ends of the pintle rod 42 may be simply headed or equipped with terminal nuts, or otherwise terminated, so as not to be easily displaced.

The cultivator tooth bars 45 are provided at their forward ends with sheet metal loops or hinge barrels 45 which extend between the eyes 41 and receive they pintle rod 42. These barrels 45V are formed by doubling a piece of sheet metal so that the central f' or doubled 'portion forms the barrel and the two free ends 46 are inserted into lrerfs 47 formed in the forward ends of the cultivator tooth bars. At their rear ends, the tooth bars are provided withsuitable teeth, of elected form. .Beneath the tooth bars are two lifting bars 50 mounted for swinging movement on Abrackets 51 pivoted on said pintle rod42. One such liftingbar 50vis provided for each side of themachine as indicated by the dotted lines adjacent the rear of the seat in Fig. l, and each Ysaid bar 50 is provided with `an operating lever 52, which in the Fig. 2-position occupies apositionatvthe rearof the double detent 53, or inthe Fig. l position occupies a position at-the `front of this detent 58, thereby posif tivelyv holding the tooth bars elevated 'or depressed. Y

"Since thiscultivator is designed to follow a ltwenty-toothk gra-in drill, provision must be made for cultivating `nineteen spaces between the drilled or plant rows. Teeth are provided to cultivate sixteen of these rows or spaces,'twoof the tooth barsv and their teeth being obscured iirFig. liby'the frame beams'4 under which these are located. For cultivating thefremaining of the nineteen spaces, or to be specific, the remaining three spaces or rows, provision is made whereby the two rear land single front wheels occupy these spacesor rows and by-their rolling action'serveto prevent drifting and to depress the spaces in which they roll.

It is preferable to 'adjust the two center drills of the drilling machine that this cultivatorfollows so that the'space between `the centerdrilled rows will be greater and when the v'young plants come up, be more easily distinguished so that the operator of the cultivator will have noV trouble in .always causing the front or center wheel to follow the center space row previously drilled.

K.ln operation, the driver occupies the seat and straddles the v center frame member 8-9 with his feetv on the foot rests 25. The rear end of the'guiding handle or lever 17 is elevated so that its nose 22 engages in notch 24 vof the draft tongue to cause the front wheel to turn with the draft tongue according to the direction in which the draft animals 'or tractor (if one is employed) travels. lf it be'comesnecessary for any reason to gu'ideithe machine independently of the draft tongue, or to allow the draft tongue independent swinging movement, the rear end of the guiding handle `17 is depressed to bring its nose 22 out of the recess 24 of the draft tongue and permit independent movement of the draft tongue and manual steering movement of the front wheel.

lt is needless to set forth the specific conditions under which locking or releasing of the steering head and draft tongue might be desirable, since the same will be apparent to all farmers, nor does it seem to be necessary to state that the structural details of the machine shown in the drawings are those of a model and that the saine may be modified along more conventional lines, except in the details claimed as part or substance of the invention.

Having described the invention, what is claimed as new and useful is 1. A cultivator comprising a frame, a steering device swiveled to the frame, a vertically swinging lever pivoted to the upper portion of the steering device, a draft appliance swiveled to the upper portion of the steering device, and cooperative means carried by the lever and draft appliancey whereby the said lever may be interlocked Vwith the draft appliance or free thereof to permit steering through the draft appliance or manually. Y

2. A cultivator comprising a frame, a forlr swiveled in the front end portion of the frame, wheel journaled in the fork, a lever pivoted on the upper lend portion ofthe fork, a draft tongue swiveled on the upper end portion of the forli, meansfor interlocking the lever with'the draft Vtongue to permitsteering by the draft tongue'` when these parts are engaged or manually through the lever when these parts are disengaged, a seat on the frame, and vfoot rests onV the furet-ations of the fork.

3. A cultivator comprising a frame, a steering head swiveled in the frame, a wheel journaled in the steering head,a hand lever secured to the steering head by which the steering head and wheel may be turned for guiding action, a draft appliance swiveled on the head adapted to be interlocked with the said lever when it is desired to turn the steering head and wheel by the draft appli- Y ance, a pair of trees, one on each side :of

the steering head, and a ieXible draft member attached at its ends to eachtree and eX- tending through a guide member from one side to the other of the cultivator.

ln testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
